Send
When a push campaign is published, Iterable will attempt to send a push to all devices registered for the contacts receiving the push. That total number of pushes attempted to all devices registered but not currently disabled will show up as the Total Pushes Sent.
Unique Pushes Sent represents the total number of contacts that were sent the push. If a contact has more than one enabled device, both devices will be sent the push, but the Unique Pushes Sent will only count at a user level.
Bounce
If a push notification is sent to a device with a disabled token/regId, Apple or Google will register the event as a bounce and provide feedback to Iterable. A token/regId can become disabled due to a variety of reasons such as when a user uninstalls the app, the app or token is no longer valid, the user reinstalled their OS or upgraded to a new OS (less frequent case).
When a push notification is sent to a device that has disabled push notifications, this will not count as a bounce.
The bounce reporting on the campaign metrics page will also include app uninstalls that occurred after the campaign was sent. Iterable measures this by sending a "ghost push" after the actual campaign.
On the user profile view, you will be able to see bounce and uninstall events as two different events.
Delivery
The total pushes delivered is the total pushes sent minus the total pushes bounced. Therefore, the push delivery rate is (total pushes sent - total pushes bounced)/(total pushes sent).
Open
When a user clicks on a push notification, Iterable's mobile SDKs automatically
track a push open event. If you're not using Iterable's mobile SDKs, you can
manually track a push open event by calling POST /api/events/trackPushOpen.
Uninstall
Iterable will track uninstalls with no additional work by you.
Uninstalls only happen when we get a bounce, so if a recipient has merely disabled notifications from their device settings, push messages will be received successfully by the device, but will not be displayed to the recipient.
To track uninstalls, Iterable sends a silent push notification, or "ghost" push, some time (currently, 12 hours) after a campaign has been sent. Based on this silent push notification, if Iterable receives feedback that the device token is no longer valid, it assigns an uninstall to the device attributed to the prior campaign.
Similarly, if a "real" push campaign uncovers an invalid device token, it will also check for a prior campaign, within the last 12 hours, to attribute that previous campaign as the cause for the uninstall. If there was no recent campaign, Iterable still tracks the uninstall, but does not attribute it to any campaign.
Unsubscribe
Since a push does not require an opt-out directly in the message like an
email would, we allow each company to define the events that would constitute
a push unsubscribe and send the event directly through Iterable's
POST /api/users/updateSubscriptions
API.
When the unsubscribe event is sent, the body of the call should include the
email of the contact, the campaignId, and either the channelId or
messageTypeId (depending on how unsubscribes are managed in your Iterable
account). If you are setting up your Iterable account, read
Message Channels and Types Best Practices.
